[Renal fistula as preparation for ureteral reconstruction]

A female patient is described in whom during caesarean section the lower segment of the left ureter was injured with development of ureterovaginal fistula and left-sided hydronephrosis. The creation of temporary renal fistula by percutaneous renal puncture removed the urine from the hydronephrosis and made possible delaying of ureteral reconstruction for 3 months.
